Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings of the embodiments of the present disclosure. It is to be understood that the described embodiments are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the disclosure without any inventive step, are within the scope of protection of the disclosure.

Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure belongs. The use of "first," "second," and similar terms in this disclosure is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. Likewise, the word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.

For slotting operation with small depth or low hardness, the slotting device with the cutting wheel has high efficiency, thereby having wide application. However, in the grooving work with a small depth and high hardness, the cutting wheel requires a large rotational driving force, and therefore, the cutting wheel generates a large traction force to the grooving apparatus during the rotational cutting. If the friction force between the slotting device and the ground is smaller than the transverse traction force of the cutting wheel to the slotting device, the slotting device can move abnormally in the operation process, and the cutting wheel is damaged or even a safety accident occurs.

The problem of the transverse traction force can be solved by adopting a double-wheel slotting device. The double-wheel grooving device comprises two cutting wheels, wherein the rotation directions of the two cutting wheels are opposite, so that the transverse traction forces generated by the two cutting wheels can be mutually offset or reduced. The common two-wheel grooving device is mainly designed for grooves with large grooving depth, the grooving depth of the grooves usually exceeds 50 meters, and the common two-wheel grooving device comprises a carrier, a grooving part and a lifting part. The carrier carries the fluting part through the lifting unit and cuts the slot and controls the cutting depth. The lifting component is a winding component comprising a steel wire rope. The slotting component comprises two wheel cutting, a cutting frame and a slurry pump. The double-wheel cutting device and the mud pump are fixedly arranged on the cutting frame, the cutting frame is connected with the steel wire rope, and the winding component controls the slotting component to move up and down by rolling up or loosening the steel wire rope. The cutting frame may be rectangular and a counterweight is fixedly connected to the cutting frame to allow the cutting wheel to have a large contact pressure with a grooving object, such as a rock formation, and the grooving part realizes vertical downward cutting mainly by gravity. Because the steel wire rope can only control the up-down direction, the control capability to other directions is limited, a guide groove is usually required to be manufactured on the surface of a rock stratum which is just started to operate, the undercutting speed is not too fast, the process is complex and the efficiency is low for the positioning stage, the depth of the stage is about 2 meters to 5 meters, the depth can be different according to actual conditions, the influence is limited in the operation with larger depth, but in the grooving operation with smaller depth, the common double-wheel grooving device has no practicability because of the low efficiency due to the uncertainty of the surface shape of a grooving object.

In order to solve the above technical problem, an embodiment of the present disclosure provides a slotting device, which can improve slotting efficiency and reduce slotting cost.

for convenience of description, in some of the drawings, "up", "down", "front", "rear" is given, and in the embodiment of the present disclosure, the vertical direction is a direction from top to bottom, the vertical direction is a direction of gravity, the horizontal direction is a direction perpendicular to the vertical direction, the horizontal direction from right to left is a direction from front to rear, and the upper vehicle body 53 (see fig. 1) is a direction transverse to the rotation direction of the lower vehicle body 54 (see fig. 1).

In the embodiment of the present disclosure, the grooving object is taken as a rock stratum as an example, it is understood that the grooving object is not limited to the rock stratum, and may also be a concrete layer, an ice layer, and the like.

Fig. 1 is a schematic structural diagram of a slotting device provided in an embodiment of the present disclosure. As shown in fig. 1, the grooving apparatus 1a includes a cutter wheel holder 1, a first cutter wheel 41, a second cutter wheel 42, and a cutter arm 2. The cutting wheel support 1 and the first cutting wheel 41 are hinged to a first hinge point 01, and the cutting wheel support 1 and the second cutting wheel 42 are hinged to a second hinge point 02. The cutting wheel holder 1 and the cutting arm 2 are hinged to a third hinge point 03. Both the first hinge point 01 and the second hinge point 02 are rotatable relative to the third hinge point 03. The first and second hinge points are both rotatable relative to the third hinge point, i.e. the cutting wheel holder is rotatable relative to the cutting arm about the axis of the third hinge point, enabling the swinging of the first and second cutting wheels 41, 4 in the up-down direction as well as in the front-back direction. So, make the relative height-adjustable of first pin joint and second pin joint to make the relative height-adjustable of first cutting wheel and second cutting wheel, can improve the adaptability of fluting device to the topography, improve fluting efficiency, reduce fluting cost.

For example, in a grooving operation with a depth not very deep (typically within 3 meters), due to the uncertainty of the surface shape of the rock formation, the relative heights of the first cutting wheel 41 and the second cutting wheel 42 are adjusted more frequently, and the grooving apparatus provided by the embodiment of the disclosure can adjust the relative heights of the first cutting wheel 41 and the second cutting wheel 42, reduce the difference of the cutting amounts of the rock formation by the first cutting wheel 41 and the second cutting wheel 42, thereby improving the cutting effect or reducing the lateral traction force generated to the carrier 5 when the cutting wheels rotate.

The relative height of an element being adjustable may mean that the height of the element relative to a plane may be varied. For example, the relative height adjustment of the first hinge point and the second hinge point includes the relative height adjustment of the first hinge point and the relative height adjustment of the second hinge point, and the relative height adjustment of the hinge points may refer to the height adjustment of the hinge points with respect to the same plane or may refer to the distance adjustment of the hinge points with respect to the same plane. For example, the same plane includes the ground, but is not limited thereto, and comparison references other than the ground may be used.

In some embodiments of the present disclosure, as shown in fig. 1, the connecting lines between the first hinge point 01, the second hinge point 02, and the third hinge point 03 constitute a triangle, but are not limited thereto. First pin joint 01, second pin joint 02 and third pin joint 03 also can form a straight line, and third pin joint 03 is located between first pin joint 01 and second pin joint 02, also can realize that cutting wheel support 1 swings around third pin joint 03. In order to make the structure compact, the embodiment of the present disclosure is described by taking an example that the connecting lines between the first hinge point 01, the second hinge point 02, and the third hinge point 03 form a triangle.

For example, the cutting wheel carrier 1 includes a cutting wheel carrier body 10, and the cutting wheel carrier body 10 includes a first hinge hole, a second hinge hole, and a third hinge hole.

In some embodiments of the present disclosure, the cutting wheel holder 1 comprises two cutting wheel holder bodies 10, and the two cutting wheel holder bodies 10 are symmetrically disposed at both sides of the cutting arm 2. For example, the two cutting wheel supports 1 are symmetrically arranged on both sides of the plane formed by the first cutting wheel 41 and the second cutting wheel 42.

In some embodiments of the present disclosure, as shown in fig. 1, the angle between the line connecting the third hinge point 03 and the first hinge point 01 and the line connecting the third hinge point 03 and the second hinge point 02 is an obtuse angle. For example, to facilitate cutting and better terrain conformity, the obtuse angle is less than or equal to 150 °. Of course, the angle of the included angle needs to be calculated by combining the diameter of the first cutting wheel, the diameter of the second cutting wheel, the distance between the first cutting wheel and the second cutting wheel, and other relevant parameters, and may also be greater than 150 °, and if the third hinge point 03 is disposed at a higher position, such as a position higher than the cutting arm, and the diameters of the first cutting wheel 41 and the second cutting wheel 42 are smaller, the included angle may be smaller than 90 °, which is not limited by the disclosure.

In some embodiments of the present disclosure, as shown in fig. 1, the slotting device 1a further includes a carriage cylinder 3. One end of the support oil cylinder 3 is hinged with the cutting wheel support 1 through a first hinged shaft, and the other end of the support oil cylinder 3 is hinged with the cutting arm 2 through a second hinged shaft. For example, the cutting arm 2 includes a fourth hinge point 04, and the holder cylinder 3 is hinged to the fourth hinge point 04 with the cutting arm 2 through a second hinge shaft. For example, the grooving apparatus 1a includes two carriage cylinders 3 symmetrically disposed on both sides of the cutting arm 2.

In some embodiments of the present disclosure, as shown in fig. 1, the fourth hinge point 04 is located at a lower portion of the cutting arm 2, but the location of the fourth hinge point 04 is not limited thereto. For example, the position of the fourth hinge point 04 may be suitably adjusted up or provided to the cutting arm body 20, as compared to that shown in fig. 1. The embodiment of the present disclosure does not limit the position of the fourth hinge point 04.

In some embodiments of the present disclosure, as shown in fig. 1, one end of the support cylinder 3 is hinged to the first hinge point 01 with the cutting wheel support 1. It can be understood that the bracket oil cylinder 3 can also be adjusted to be hinged to the second hinge point 02 with the cutting wheel bracket 1, so that the hinge point of the bracket oil cylinder 3 and the bracket and the first hinge point 01 or the second hinge point 02 can share one position, thereby enabling the structure to be more compact and being beneficial to reducing the manufacturing cost, such as reducing the connecting shaft and the like.

The support cylinder 3 can also be hinged with other parts of the cutting wheel support 1, and the hinged part of the support cylinder 3 and the cutting wheel support 1 is not limited to the first hinged point 01 and the second hinged point 02.

For example, the carriage cylinder 3 may be a hydraulic drive system. For example, the hydraulic drive system includes a hydraulic pump, a controller, and a telescopic rod, etc. The telescopic rod comprises a telescopic part and a fixing part, wherein one part of the telescopic part is positioned in the fixing part, and the other part of the telescopic part is exposed out of the fixing part. The telescopic part can slide in the fixed part to adjust the length of the telescopic rod, so as to adjust the distance between two end points connected by the bracket oil cylinder, for example, adjust the distance between the first hinge point 01 and the fourth hinge point 04 in fig. 1, so as to adjust the height of the first hinge point 01 relative to the fourth hinge point 04 in the up-down direction, namely, adjust the rotating angle of the cutting wheel bracket relative to the cutting arm around the third hinge point. Therefore, the swing amplitude of the cutting wheel bracket 1 can be controlled, the up-and-down adjustment of the first cutting wheel 41 and the second cutting wheel 42 is realized, and the swing range and the cutting position of the cutting wheel bracket are further controlled.

The above-described holder cylinder 3 is a holder actuator, but the holder actuator is not limited to the holder cylinder 3. The drawings of the present disclosure illustrate a bracket actuator as the bracket cylinder 3. For example, one end of the carriage driver is connected to the cutting wheel carriage and the other end of the carriage driver is connected to the cutting arm.

In some embodiments of the present disclosure, the support cylinder 3 may also be a hydraulic motor or an electric motor, and the cutting wheel support 1 is driven to swing by the hydraulic motor or the electric motor. The specific mode is that a hydraulic motor or a motor is fixedly connected to the cutting arm 2, a first gear is arranged at the end of the hydraulic motor or the motor, a second gear is arranged on the cutting wheel support 1, the first gear is meshed with the second gear, the hydraulic motor or the motor rotates to drive the cutting wheel support 1 to swing, the swing amplitude of the cutting wheel support 1 can be limited according to actual needs, and therefore the up-and-down adjustment of the first cutting wheel 41 and the second cutting wheel 42 can be achieved. Of course, the manner of driving the cutting wheel support 1 to swing is not limited thereto, and the disclosure does not limit this.

Fig. 2 is an enlarged schematic view of the first stroke chamber 22 of the notching apparatus of fig. 1. As shown in fig. 1 and 2, the cutting arm 2 includes a first stroke chamber 22, and the first stroke chamber 22 includes a first end 221 and a second end 222. The first end portion 221 and the second end portion 222 are opposite ends in the extending direction of the first stroke chamber 22, and the fourth hinge point 04 (e.g., a hinge shaft of the fourth hinge point) is movable along the first stroke chamber 22 between the first end portion 221 and the second end portion 222. First stroke chamber makes the fourth pin joint no longer fixed, has had certain activity space, and so design is favorable to the relative height of support hydro-cylinder regulation first cutting wheel and second cutting wheel to make the cutting wheel can adapt to the topography better in limited swing space, can make first cutting wheel and second cutting wheel have stable contact pressure with the fluting object (waiting to cut the thing, including rock or concrete etc.) under the complicated operating mode of topography, thereby reinforcing fluting device's operating mode adaptability. For example, in the limited swing space, the terrain adaptation of the grooving apparatus does not usually need to be controlled manually, but rather, the grooving apparatus slides automatically through the fourth hinge point 04 relative to the force applied by the cutting arm 2 in a direction related to the contact of the first cutting wheel 41 and the second cutting wheel 42 with the grooving object, for example, when the first cutting wheel 41 is in contact with the grooving object and the second cutting wheel 42 is not in contact with the grooving object, the fourth hinge point 04 slides to the second end 222 close to the first cutting wheel 41 until the fourth hinge point 04 is no longer applied with force or until the fourth hinge point 04 is in contact with the second end 222; for example, when the second cutting wheel 42 contacts the slotting object and the first cutting wheel 41 does not contact the slotting object, the fourth hinge point 04 slides to be close to the first end 221 of the second cutting wheel 42 until the fourth hinge point 04 is not stressed or until the fourth hinge point 04 contacts the first end 221; the distance from the first end 221 to the second end 222 cannot be too large, and a large adjusting position should be completed by matching with the support cylinder 3, so as to avoid that when the cutting wheel preprocesses the terrain needing to be corrected, the free sliding stroke is too large, and the stroke which can be controlled by the support cylinder 3 is too small, which is not beneficial to operation. For example, the length of the first stroke chamber 22 is more than 2 times the diameter of the hinge shaft (the hinge shaft of the fourth hinge point) located therein. For example, in order to avoid the stroke of the free sliding from being excessively large, the length of the first stroke chamber 22 is 3 to 5 times the diameter of the hinge shaft (the hinge shaft of the fourth hinge point) located therein, but is not limited thereto. For example, the distance from the first end 221 to the second end 222 can be set according to different types of slotting devices.

In some embodiments of the present disclosure, the first stroke chamber 22 may extend in a front-back direction (as shown in fig. 1), in an up-down direction, or in an inclined direction having an inclination angle with respect to both the front-back direction and the up-down direction.

For example, when two cutting wheel holders are provided, two first-stroke chambers 22 are also provided. Thus, two symmetrical cutting wheel holders 1 and two first stroke chambers 22 are formed with respect to the first cutting wheel 41 and the second cutting wheel 42, but not limited thereto.

In addition to the above-described oscillation of the cutting wheel in the up-down direction and the front-back direction, in some embodiments the cutting wheel may also be rotatable about an axis in the vertical direction. For example, fig. 3 is a schematic structural diagram of a slotting device including a rotating cylinder and a rotating mechanism according to an embodiment of the present disclosure. The placing positions of the first cutting wheel and the second cutting wheel can be adjusted by rotating the oil cylinder and the rotating mechanism. The configuration shown in fig. 3 may be the state of the slotting device before rotation.

Fig. 4 is a schematic structural view of another state of the slotting device shown in fig. 3. The configuration shown in fig. 4 may be the state of the slotting device after rotation. The different placement positions of the first cutting wheel and the second cutting wheel shown in fig. 3 and 4 can increase the adjustment capability of the position of the cutting wheel, and further increase the capability of the slotting device to adapt to different working conditions.

Fig. 5 is an exploded schematic view of a slotting device according to an embodiment of the disclosure. The slotting device shown in fig. 5 can be an exploded structure schematic view of the slotting device shown in fig. 3.

Fig. 6 is a schematic view of another structure of the slotting device shown in fig. 3.

The grooving apparatus including the rotation cylinder and the rotation mechanism will be described below with reference to fig. 3 to 6.

as shown in fig. 3 to 6, the slotting device 1b further includes a rotary actuator (the rotary actuator is taken as the rotary cylinder 4 for detailed description). The cutting arm 2 comprises a cutting arm main body 20 and a rotating mechanism 23, one end of the rotating oil cylinder 4 is hinged to the fifth hinge point 05 together with the rotating mechanism 23, and the other end of the rotating oil cylinder 4 is hinged to the sixth hinge point 06 together with the cutting arm 2. The rotating mechanism 23 is hinged to the third hinge point 03 with the cutting wheel support 1, and the rotating mechanism 23 is also hinged to the seventh hinge point 07 with the cutting arm main body 20 of the cutting arm 2 (see fig. 5). For example, the rotating mechanism 23 and the cutting wheel holder 1 have mating surfaces for limiting the rotation of the cutting wheel holder 1 relative to the rotating mechanism 23 only about the third hinge point 03. One end of the rotating oil cylinder 4 is hinged with the rotating mechanism 23, and the other end of the rotating oil cylinder 4 is hinged with the cutting arm main body 20. For example, in some embodiments, the grooving apparatus includes a rotary cylinder 4.

For example, a rotary drive is fixed to the cutting arm body 20 or the rotating mechanism 23, and the rotary drive drives the rotating mechanism 23 to rotate relative to the cutting arm body 20 to adjust the placement angle of the cutting wheel holder 1 relative to the cutting arm body 20.

For example, the rotating cylinder 4 drives the rotating mechanism 23 to rotate around the seventh hinge point 07 through extension and contraction, and the cutting wheel bracket 1 rotates along with the rotating mechanism 23 to generate the same rotation, so as to adjust the placing angle of the cutting wheel bracket relative to the cutting arm main body 20. So, can further increase the home range of cutting wheel, further increase the operation flexibility of fluting device to further increase the operating mode adaptability of fluting device.

the above description has been given by taking the pivot actuator as the pivot cylinder 4, but the pivot actuator is not limited to the pivot cylinder 4. The rotary drive may also be a hydraulic motor or an electric motor.

In some embodiments of the present disclosure, the cutting wheel holder 1 is placed at an angle ranging from 0 ° to 90 ° with respect to the cutting arm body 20. That is, the cutter wheel holder 1 is rotatable in the range of 0 ° to 90 °. For example, fig. 3 shows the cutting wheel holder 1 disposed at an angle of 0 ° with respect to the cutting arm body 20, and fig. 4 shows the cutting wheel holder 1 disposed at an angle of 90 ° with respect to the cutting arm body 20. The angle of placement of the cutting wheel holder 1 relative to the cutting arm body 20 may also be any value from 0 ° to 90 °, for example, the angle of placement of the cutting wheel holder 1 relative to the cutting arm body 20 may also be 30 °, 45 ° or 60 °. The angle of the cutting wheel support 1 of the slitting device placed relative to the cutting arm body 20 is not limited and may be determined as desired.

Of course, the slotting device can be in the state shown in fig. 3 during the walking process, and the placing angle of the cutting wheel bracket 1 relative to the cutting arm main body 20 is not 0 during the operation process, so as to facilitate the movement and the operation of the slotting device.

In some embodiments of the present disclosure, as shown in fig. 3 (see also fig. 1), the grooving apparatus further includes a first cutter wheel driving part 43 and a second cutter wheel driving part 44, the first cutter wheel driving part 43 and the second cutter wheel driving part 44 are fixedly connected to the cutter wheel bracket 1, the first cutter wheel driving part 43 is configured to drive the first cutter wheel 41 to rotate about the first hinge point 01, and the second cutter wheel driving part 44 is configured to drive the second cutter wheel 42 to rotate about the second hinge point 02. The first cutting wheel driving part 43 is in gear engagement with the first cutting wheel 41, and the second cutting wheel driving part 44 is in gear engagement with the second cutting wheel 42.

One end of the rotating oil cylinder 4 is hinged to the fifth hinge point 05 together with the rotating bracket 232, and the other end of the rotating oil cylinder 4 is hinged to the sixth hinge point 06 together with the cutting arm main body 20. The rotary seat 231 and the cutting wheel support 1 are hinged to the third hinge point 03, and the rotary seat 231 and the cutting arm main body 20 of the cutting arm 2 are hinged to the seventh hinge point 07 (as shown in fig. 5). The rotary oil cylinder drives the rotary bracket 232 to rotate through telescoping, so that the rotating angle of the rotary seat 231 is controlled, and the placing angle of the cutting wheel bracket 1 is adjusted.

The structure of the rotary seat 231 and the connection relationship of the rotary seat 231 with the cutting arm main body 20 of the cutting arm 2 can be seen more intuitively from fig. 5.

In some embodiments of the present disclosure, as shown in fig. 1, 3 to 6, the slotting device further includes a carrier 5 and a lift cylinder 6. One end of the lift cylinder 6 is hinged to the eighth hinge point 08 with the cutting arm 2 through a third hinge shaft 29 (as shown in fig. 1 and 3), and the other end of the lift cylinder 6 is hinged to the ninth hinge point 09 with the carrier 5. The cutting arm 2 is hinged to the tenth hinge point 010 with the carrier 5, the cutting arm 2 further comprising a second stroke chamber 31. The carrier can provide power for the slotting device and can enable the slotting device to have the moving capacity relative to the ground.

As shown in fig. 3 to 6, the slotting device 1b can also be provided with a first stroke cavity 22, which can be described with reference to the first stroke cavity 22 in the slotting device 1a and will not be described herein again.

Fig. 7 is a schematic structural diagram of a cutting arm according to an embodiment of the disclosure. As shown in fig. 7, the cutting arm 2 includes a first receiving chamber 32 and a second receiving chamber 33, the first receiving chamber 32 having a first opening 321, and the second receiving chamber 33 having a second opening 331. The cutting arm 2 further comprises an aperture 30 configured to pass the hinge shaft of the rotating seat 231 therethrough to hinge the rotating seat 231 with the cutting arm body 20 of the cutting arm 2. The first housing chamber 32 is configured to house at least a portion of the first cutting wheel 41 and the second housing chamber 33 is configured to house at least a portion of the second cutting wheel 42. Referring to fig. 6 and 7, the first and second receiving cavities 32 and 33 are located above the first and second cutting wheels 41 and 42. The arrangement can save the upper and lower spaces of the slotting device and enlarge the diameter range of the cutting wheel. In order to ensure that the cutting arm body of the cutting arm has high strength, particularly bending strength in the vertical direction, the thickness in the vertical direction is often set to be thick, which easily occupies more vertical space. The space about the fluting device is limited, and the inner space at the cutting arm sets up and holds the chamber, can save the space of upper and lower direction under the prerequisite of the structural strength of the cutting arm main part of guaranteeing the cutting arm, is favorable to setting up the cutting wheel of great diameter.

Fig. 8 is an enlarged structural schematic view of a second stroke cavity of the slotting device provided by an embodiment of the disclosure. As shown in fig. 8, the second stroke chamber 31 (see also fig. 1, 3 to 6) includes an upper end 311 and a lower end 312, the upper end 311 and the lower end 312 are opposite ends in the extending direction of the second stroke chamber 31, and the eighth hinge point 08 (the third hinge shaft 29) is movable along the second stroke chamber 31 between the upper end 311 and the lower end 312. The third hinge axis 29 may also be referred to as a lifting axis. The upper end 311 may be referred to as a third end, and the lower end 312 may be referred to as a fourth end. For example, the maximum straight-line distance from the upper end 311 to the lower end 312 of the second stroke chamber 31 is 2 times or more the diameter of the shaft (third hinge shaft 29) therein. For example, in order to obtain a large free stroke, the maximum linear distance from the upper end portion 311 to the lower end portion 312 is 5 times or more the diameter of the hinge shaft therein, but is not limited thereto. The maximum linear distance from the upper end 311 to the lower end 312 may depend on the depth of the slot.

the working principle of the second stroke cavity is as follows: extending the lifting oil cylinder 6 to drive the third hinge shaft 29 to contact with the upper end 311; continuing to extend the lifting oil cylinder 6 to drive the cutting arm 2 to lift, and matching the cutting arm with the traveling mechanism or the bracket oil cylinder to enable the cutting wheel bracket to be positioned above a slotting object such as a target rock stratum or a concrete layer; the lift cylinder 6 is shortened to create a gap between the third hinge shaft 29 and the upper end 312. The height of the gap needs to meet the grooving depth, and the height of the gap can be adjusted in the grooving process to meet the grooving depth. At this time, the contact pressure of the cutting wheel with the grooving object comes completely from the gravity of the grooving apparatus. Since the slotting device gravity is stable, the slotting force of the slotting device is also stable. The stable undercut force is beneficial to improving the slotting efficiency and reducing the damage of the cutting device.

In some embodiments of the present disclosure, referring to fig. 1, 3 to 6, the eighth hinge point 08 is located between the third hinge point 03 and the ninth hinge point 09. So set up, be favorable to make full use of the lift of lifting cylinder.

In some embodiments of the present disclosure, as shown in fig. 1, 3-6, to reduce the traction, the first cutting wheel 41 and the second cutting wheel 42 rotate in opposite directions. The two cutting wheels rotate in opposite directions, so that the transverse traction force generated by the two cutting wheels is small, and even can be offset, and the double-wheel grooving device is suitable for grooving operation with small depth and high hardness.

Fig. 9 is a schematic view of a slotting device provided in an embodiment of the present disclosure. As shown in fig. 9, the lifting cylinder 6 lifts the cutting arm 2, and the cutting wheel support 1 can swing around the third hinge point 03 with a certain amplitude under the driving of the support cylinder 3, so that the first cutting wheel 41 is higher than the second cutting wheel 42. When the rotating mechanism is provided, the first cutting wheel 41 and the second cutting wheel 42 are adjusted, and the placing positions of the two cutting wheels can be adjusted by the rotating mechanism. Then, make two cutting wheels and fluting object contact, when two cutting wheels and fluting object contact, because of the setting of third hinge point 03, do benefit to the adaptation topography. And the lifting oil cylinder 6 is retracted, so that the two cutting wheels have stable undercutting force, the first cutting wheel and the second cutting wheel work simultaneously during grooving operation, and the undercutting force distributed by the gravity of the cutting arm on the two cutting wheels is approximately uniform, so that the undercutting force of the grooving operation is relatively stable. The first cutting wheel driving part 43 and the second cutting wheel driving part 44 are started to perform slotting, and the rotation directions of the two cutting wheels are opposite, so that the transverse traction force on the carrier when the cutting wheels rotate is reduced. The support oil cylinder 3 can be adjusted before or during grooving operation to adjust the swing amplitude of the cutting arm support 1, and further adjust the swing of the cutting wheels in the front-back direction and the up-down direction, so that the two cutting wheels adapt to the terrain during grooving. Therefore, the relative height of the two cutting wheels can be adjusted by the aid of the cutting wheel supports, and working condition adaptability of the slotting device is improved.

In some embodiments of the present disclosure, as shown in fig. 1, 3-6, and 9, the grooving apparatus further includes a counterweight 7, the counterweight 7 being located on the cutting arm 2 or the cutting arm body 20 of the cutting arm 2. The counterweight can increase the contact pressure of the cutting wheel on a slotting object such as rock strata or concrete layers, thereby enhancing the cutting capability of the cutting wheel.

In some embodiments of the present disclosure, as shown in fig. 1, 3-6, and 9, the grooving apparatus further comprises a driver 35, and the cutting arm 2 or the cutting arm body 20 of the cutting arm 2 comprises a counterweight track 34. The counterweight 7 is slidably connected to the cutting arm 2 by a counterweight track 34. The counterweight driver 35 is configured to drive the counterweight 7 to slide relative to the cutting arm 2 along the extension direction of the counterweight track 34. In general, the hardness of a slotting object such as a rock stratum is complicated to change, and the contact pressure of a cutting wheel on the slotting object needs to be adjusted according to different working conditions so as to maintain reasonable contact pressure. The counterweight can slide along the counterweight track, and the adjusting capability of the slotting device to the contact pressure can be improved, so that the working condition adaptability of the slotting device is further improved.

In some embodiments of the present disclosure, as shown in fig. 1, 3 to 6, the weight rail 34 includes a first end 341 and a second end 342, the first end 341 is closer to the tenth hinge point 010 than the second end 342, and the first end 341 is beyond the tenth hinge point 010, i.e., the first end 341 is located at the left side of the tenth hinge point 010.

As shown in fig. 3, a vertical line passing through the tenth hinge point 010 is a first boundary line 71, and in some embodiments of the present disclosure, the counterweight 7 is configured to be slidable to a side of the first boundary line 71 away from the second hinge point 02. The reason for this is that: the weight accounts for a relatively large proportion of the total weight of the slotting device and therefore the position of the weight has a relatively large influence on the balancing of the slotting device. When the slotting device is in a non-working state, such as a static or walking state, the counterweight is positioned behind the first boundary line 71, i.e. to the left of the first boundary line 71 in fig. 3, which is beneficial for keeping the slotting device balanced; when the slitting device is in operation, the contact pressure of the cutting wheels against the rock formation is increased and the counterweight is located behind the first dividing line 71.

As shown in fig. 3, by having the vertical line of the point of the cutting wheel closest to the second end 342 of the counterweight track 34 that is furthest from the tenth hinge point 010 be the second dividing line 72, in some embodiments of the present disclosure, the counterweight is configured to be slidable to the side of the second dividing line 72 that is furthest from the tenth hinge point 010 to obtain a larger undercut force. In the embodiments of the present disclosure, the vertical line is always vertical, and is the same as the direction of gravity.

The arrangement of the sliding weight can further enhance the balance of the carrier and the cutting capability of the cutting wheel for different rock strata.

For example, in operation, the cutting arm 2 forms two pivot points, one is the tenth hinge point 010, the other is the contact point of the two cutting wheels with the slotting object 40, the contact point is simplified to be a point for analysis, the weight of the cutting arm 2 can be only partially distributed to the two cutting wheels according to the force resolution, the weight obtained by the two cutting wheels is related to the position of the center of gravity of the cutting arm 2, and the closer the center of gravity is to the two cutting wheels, the larger the weight obtained by the cutter when the cutting arm 2 has the same weight.

In some embodiments of the present disclosure, as shown in fig. 3 and 4, the slotting device further comprises a first position-limiting part 36, and the first position-limiting part 36 is fixedly arranged on the cutting arm 2. The first stopper 36 includes a first end 361 and a second end 362. For example, first end 361 is located at the leftmost side of counterweight track 34 and second end 362 is located at the rightmost side of counterweight track 34. The purpose of the first end 361 and the second end 362 is to prevent the counterweight from sliding out of the counterweight track 34 on the cutting arm 2.

In some embodiments of the present disclosure, as shown in fig. 3 and 4, the slotting device further includes a second limiting portion 37, and the second limiting portion 37 is fixedly disposed on the carrier 5. The reason for this is that: as shown in fig. 3 and 4, in order to expand the adjustment range of the center of gravity of the sliding weight, the cutting arm is usually configured to be long, when the lifting height of the cutting arm is too high, the left end of the cutting arm is likely to collide with other components (such as a distribution valve and a pipeline, not shown in the figure) to damage the relevant components, and the second limiting portion can limit the lifting height of the cutting arm, so that the cutting arm can not damage the relevant components in the lifting range, and can meet the lifting height requirement. In addition, this problem can also be solved by using the stroke setting of the lift cylinder 6, for example, when the lift cylinder is fully extended, the relevant parts will not touch.

Of course, in the embodiment of the present disclosure, the counterweight 7 may not be provided. Under the condition, the slotting objects can be arranged by using a broken hammer before slotting operation so as to meet the requirement of the slotting device on the terrain, but the slotting device without a counterweight has higher practicability and reliability in places with smaller rock hardness change and flatter terrain, has low requirement on the traction force provided by the carrier and has relatively higher slotting efficiency.

In some embodiments of the present disclosure, as shown in fig. 1, 3 to 6, and 9, the vehicle 5 includes an upper vehicle body 53 and a lower vehicle body 54, the upper vehicle body 53 is rotatably connected to the lower vehicle body 54, and the lower vehicle body 54 is provided with a traveling mechanism 541. For example, the vehicle 5 is an excavator, and the body of the excavator can power the grooving device and provide the grooving device with flexible movement capability. In addition, the excavator is a great-capacity engineering machine and is characterized by flexible operation, mature technology and low use cost, the cost can be saved by using the excavator body as a carrier, and the working condition adaptability of the slotting device is improved.

The carrier can also be a vehicle body of a ditcher with an upper vehicle body and a lower vehicle body which are integrally arranged, and is provided with a power part, a control part and a traveling mechanism, wherein the power part provides power sources for the traveling mechanism and the slotting device, the traveling mechanism can drive the slotting device to move, the control part controls the actions of the slotting device and the traveling structure, the carrier can also be a bulldozer and a loader which are modified, and can also be other power equipment with traveling, so long as the power sources can be provided for the slotting device and the equipment with the slotting device can be carried.

The carrier is configured to carry a load, for example, the load includes a power portion, a hydraulic portion and a control portion, the power generated by the power portion drives the hydraulic portion to generate hydraulic oil with higher pressure, and the hydraulic oil drives the driving portion to drive the cutter to rotate so as to cut the slotting object. The carrier may provide cutting power to the cutting arm.

For example, a hinge point refers to a position where two components are connected, and usually includes a hole, a contact surface, a connecting shaft, and the like, which are required when the components are connected, and the hole of at least one component rotates relative to the connecting shaft.

features of the same embodiment of the disclosure and of different embodiments may be combined with each other without conflict.
